Ontario has been playing an important role, with world-leading science organizations including the Canadian Institutes for Health Research, the National Research Council and Genome Canada. These organizations are partnering directly with firms to lead innovation, drive discovery and have a diversified mix of industry, academia, and supply chains to support a rich environment for R&D, innovation, commercialization, and production. Many small and medium sized Ontario defence companies are heavily engaged in R&D, in niche technology areas such as unmanned vehicles, advanced sensor systems, electronic warfare, and cyber security.

Ontario is home to leading government research centres, including the National Research Council Institute for Aerospace Research, the Canadian Space Agency’s David Florida Laboratory, the Defence Research and Development Canada (DRDC) facilities in Ottawa and Toronto and the Fraunhofer Institute in London. Other specialized centres such as the Ontario Centre of Innovation and the province’s network of Regional Innovation Centres offer resources such as commercialization and advisory support along with R&D matchmaking. They work with companies in various industries such as communications and IT, energy, aerospace, manufacturing, and life sciences.

The federally run Defence Research and Development Canada operates eight research centres across Canada, each with a unique combination of expertise and facilities to carry out world-class science and technology research. Five of these centres are right here in Ontario:

  • The Toronto Research Centre
  • The Ottawa Research Centre
  • The Centre for Security Science
  • The Centre for Operational Research and Analysis
  • The Director General Military Personnel Research and Analysis

The DRDC Toronto Research Centre

DRDC Toronto is a research and development establishment for defence and national security focusing on human effectiveness, science and technology. They research individual and team performance, human to technology interaction, and the social and psychological factors that affect the resolution of conflict.

Ontario’s defence-related research organizations have produced some of the most respected work in the security field such as:

  • A virtual reality simulator developed to help helicopters land on the deck of a moving ship.
  • The STInG – Sustained Tolerance to INcreased G system that provides G protection for pilots, superior to any current operational system.
  • The Personnel Readiness and Personnel Health Protection research from DRDC Toronto’s human factors lab.
